I just wanted to expand a little on twilight's post.
For the mission, you are told Bourne has left Tangier and you need to find out where he has gone next. You have little to go on except the keyphrase from yesterday's mission Treadstone All Lies. Why not use the keyphrase & see where it leads you (A video? An image? A website?). Do not forget that there are additional tools on your agent console at your disposal.
On the top right of your Agent Console is a space where you can do Google searchs. Type in Treadstone All Lies, beneath that click on Images, then click on the Search Images button. A new screen will open with the images Google has found. If you click on the first image posted with the caption "Treadstone All Lies", you will see a newsletter from the daternotes.com site. You need to copy the URL(link) for this image (you have 3 options: A. you can either highlight & copy the URL, in green, beneath the words See full-size image, B. or you can click on the link, See full-size Image - this takes you to the daternotes.com site...highlight and copy the URL(web address) from your address bar at the top of your browser or C. You can highlight & copy it from here: http://www.daternotes.com/newsletter/newsletter.gif
Once you have the URL copied, go back to your Agent Console and scroll down to the Decryption Tool on the left. Paste the URL, you just copied, into the Image Filter and click Submit. On the bottom of the Image Filter, are 3 filters you can use: Filter A, Filter B and Filter C. You can try them all if you want, but only one them (Filter B) will give you the answer you are looking for: London.
Once you know the answer, go back to your Message Transmitter and submit your answer: London.
Don't forget to place your cameras and then let us know where you placed them and how many sightings you scored, here: http://steeplemedia.com/forums/t/10764.aspx - Good Luck!!
